Safety glasses

Safety Eyewear without fogging would encourage compliance and reduce risk of injury from a variety of hazards eg dust, radiation, electrical, chemical, biological, high-speed particles, blunt trauma, foreign objects, smoke, and the following may be employed respirators, goggles, shields, facemasks depending upon the particular situation.

Some frame and lens materials have better heat resistance and antifogging properties than others. Fire grade positive seals for protective eyewear is sometimes required

​Should safety eyewear fog up under hot or steamy conditions, it may be removed and increased exposure to a possible variety of hazards could ensue.

Sixty percent of all eye injuries happen in the workplace, so every workplace, regardless of industry, should have eye safety procedures. Many people need education in this regard. ​​

Radiation damage and the eye

UVC 100 – 280nm. Blocked by the earth’s atmosphere. No ocular absorption.
UVB 280 – 315nm. Absorbed into the cornea. UVB can directly damage skin cells’ DNA and are the main rays that cause sunburn. They are thought to cause most skin cancers. Basal cell carcinoma (BCC) is the most common cancer in the world. Eighty percent of BCCs occur in the head and neck region, of which 20 percent occur on the eyelids,
UVA 315 – 380nm. Transmitted into the ocular media. The longer the wavelength, the deeper the penetration. These rays are linked to long-term skin damage such as wrinkles, but they are also thought to play a role in some skin cancers.
Gamma rays, X-rays, and high ultraviolet radiation can be a health hazard as it penetrates the body and will transmit through spectacle glasses though it will appear denser than soft tissues. This ionising radiation can cause cell damage ( from spectroscopy studies) as opposed to the nonionising radiation of visible light wavelengths and lower.

The longer wavelength and lower energy microwaves and radio waves will penetrate the body with some absorption.

Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of visible light, ultraviolet rays, and infrared rays (also known as heat).

By complying with the Australian standards for eye protection eye injuries in the workplace that are most commonly caused by grinding and welding, usually in the fishing, construction, manufacturing, agriculture, forestry and mining industries can be avoided. ​

Ensure compliance with Australian Standards marked protection
The best assurance is the use of the Standards Mark.

​AS/NZS 1336: Recommended practices in occupational eye protection

Section 4 deals with the use of personal eye protectors in industrial settings and give examples of specific hazards together with recommended eye protection.

Section 7 deals with prescription eye protectors.

​AS/NZS 1337: Occupational eye and face protection
This Standard sets down the requirements for non-prescription eye protection.

There are four critical elements in compliant prescription eyewear.
1.) Appropriate frame
2.) Appropriate lens material and thickness
3.) Appropriate fitting
4.) Labeling and assuring compliance
